- Auto-completion dialogues may provide a user with suggestions from fragments of input text. For example “capit” may be auto-completed to “capital” or “capitulate.” Auto-completion may be implemented through, for example, web browsers, e-mail programs, search engine interfaces, source code editors, database query tools, word processors, and command line interpreters.
- Some implementations may use either a dictionary or search engine.
- the search engine may only provide suggestions that return relevant items indexed into the search engine, as opposed to a dictionary where some entries may not be present.
- the indexed data may include sensitive information.
- a search index of medical records could contain patient names or their social security numbers. Auto-completing sensitive information may be undesirable whilst completing non-sensitive information is beneficial to the search operator.
- Filtering data using only weighting or some popularity/threshold parameter (number of documents containing terms), may not provide fine enough control to prevent leaking of sensitive information. Further, providing explicit blacklists for suggestions may filter out exact term matches. However, manually providing and/or updating such a level of fine control may be cost-prohibitive, to the point where it is unlikely to be usefully applied.
- Examples may use classification technology to filter auto-complete suggestions so that users are presented only with information they are permitted to see.

Abstract
Description
- Device or systems may provide a feature called autocomplete, or word completion. Autocomplete may involve the device or system predicting a word or phrase that the user wants to type in without the user actually typing it in completely. Manufacturers, vendors, and/or service providers are challenged to provide improved autocomplete technologies to better assist the user.
- The following detailed description references the drawings, wherein:
-
FIG. 1 is an example block diagram of a device to block a term from being presented to a user; -
FIG. 2 is another example block diagram of a device to block a term from being presented to a user; -
FIG. 3 is an example block diagram of a computing device including instructions for blocking a term based on a class of the term; and -
FIG. 4 is an example flowchart of a method for blocking a term based on a class of the term. - Specific details are given in the following description to provide a thorough understanding of embodiments. However, it will be understood that embodiments may be practiced without these specific details. For example, systems may be shown in block diagrams in order not to obscure embodiments in unnecessary detail. In other instances, well-known processes, structures and techniques may be shown without unnecessary detail in order to avoid obscuring embodiments.
- Auto-completion dialogues may provide a user with suggestions from fragments of input text. For example “capit” may be auto-completed to “capital” or “capitulate.” Auto-completion may be implemented through, for example, web browsers, e-mail programs, search engine interfaces, source code editors, database query tools, word processors, and command line interpreters.
- Some implementations may use either a dictionary or search engine. The search engine may only provide suggestions that return relevant items indexed into the search engine, as opposed to a dictionary where some entries may not be present. However, in some scenarios the indexed data may include sensitive information. For example, a search index of medical records could contain patient names or their social security numbers. Auto-completing sensitive information may be undesirable whilst completing non-sensitive information is beneficial to the search operator.
- Filtering data using only weighting or some popularity/threshold parameter (number of documents containing terms), may not provide fine enough control to prevent leaking of sensitive information. Further, providing explicit blacklists for suggestions may filter out exact term matches. However, manually providing and/or updating such a level of fine control may be cost-prohibitive, to the point where it is unlikely to be usefully applied.
- Examples may use classification technology to filter auto-complete suggestions so that users are presented only with information they are permitted to see. An example device may determine a class a term from a database. The device may block the term from being presented to a user, if the determined class does not include a permission for the user to view the term. The term may suggest a remainder of an incomplete query input by the user.
- Thus, examples may allow for finer control over what elements are filtered compared to simple weight/threshold parameters. Further, examples may allow for faster deployment and less maintenance compared to a manually maintained blacklist or whitelist of exact terms/phrases/entries.
- Referring now to the drawings,
FIG. 1 is an example block diagram of adevice 100 to block a term from being presented to a user. Thedevice 100 may be a microprocessor, a controller, a memory module or device, a notebook computer, a desktop computer, an all-in-one system, a server, a network device, a wireless device, or any other type of device capable of interacting with a database and/or intercepting a message along a network. - The
device 100 is shown to include aclassification unit 110 and afilter unit 120. The classification andfilter units filter units - The
classification unit 110 may determine aclass 112 of a term from a database. The term may be a word or phrase used to describe a thing or to express a concept, such as a name, an address, and a social security number, and the like. The term may suggest a remainder of an incomplete query input by the user. Theclass 112 may relate to a system for identifying various types of terms, such as confidential and non-confidential terms. - The
filter unit 120 may block a term from being presented to a user, if thedetermined class 112 does not include apermission 122 for the user to view the term. For instance, thedetermined class 112 may indicate at least one of sensitive and personally identifiable information, if thedetermined class 112 does not includepermission 122 for the user to view the term. Thefilter unit 120 may allow the term to be presented to the user, if thedetermined class 112 includes thepermission 122 for the user to view the term. - The user may be any person who is entering a query, such as by using a computer or network service, for which the database may autocomplete with the term. The user may have a user account and/or be identified by a user name and/or password. The
permission 122 may relate to the whether the user has a right to view, access or modify the term. Thepermission 122 here may relate to whether the user may view the term triggered by the database in response to the user's query. - For instance, if the user does not have permission to view the term based on the
class 112 of the term, thefilter unit 120 may block the term by preventing the term from being sent to the user and/or denying access to the term. Thedetermined class 112 may be stored and/or associated with the term at the database, theclassification unit 110 and/or thefilter unit 120, such as via metadata. The classification andfilter units FIG. 2 . -
FIG. 2 is another example block diagram of adevice 200 to block a term from being presented to a user. Thedevice 200 may be a microprocessor, a controller, a memory module or device, a notebook computer, a desktop computer, an all-in-one system, a server, a network device, a wireless device, or any other type of device capable of interacting with a database and/or intercepting a message along a network. - The
device 200 is shown to interface with adatabase 230. Thedatabase 230 may be any electronic, magnetic, optical, or other physical storage device that contains or stores information, such as Random Access Memory (RAM), an Electrically Erasable Programmable Read-Only Memory (EEPROM), a storage drive, a Compact Disc Read Only Memory (CD-ROM), and the like. For instance, thedatabase 230 may include the most popular search terms 232-1 to 232-n, where n is a natural number, indexed from a search engine. Further, at least some of the search terms 232-1 to 232-n, may include personally identifiable information (PII), such as medical records, names, social security numbers and the like. - The
device 200 ofFIG. 2 may include at least the functionality and/or hardware of thedevice 100 ofFIG. 1 . For example, aclassification unit 210 of thedevice 200 ofFIG. 2 may include at least the functionality and/or hardware of theclassification unit 110 of thedevice 100 ofFIG. 1 and afilter unit 220 of thedevice 200 ofFIG. 2 may include at least the functionality and/or hardware of theclassification unit 120 of thedevice 100 ofFIG. 1 . - As noted above, the
classification unit 210 may determine aclass 212 of aterm 232 from thedatabase 230. Theclass 212 of theterm 232 may vary with respect to the user 250. For example, theterm 232 may be classified as confidential with respect to a first user but classified as non-confidential with respect to a second user. Thus, theclassification unit 210 may take into account a type or identify of the user 250 when determining theclass 212 of theterm 232. Different types of the users 250 may correspond to different types ofclasses 212. For instance, the user's 250 account may be used to identify the type of user, such as when the user 250 logs into a system. - As also noted above, the
filter unit 220 may block a term from being presented to a user 250, if thedetermined class 212 does not include apermission 222 for the user 250 to view theterm 232. Thefilter unit 220 may allow theterm 232 to be presented to the user 250, if thedetermined class 212 includes thepermission 222 for the user 250 to view theterm 232. - The
classification unit 210 may classify theterm 232 based on at least one of arule 214 andmachine learning 216. While onerule 214 is shown, examples may include a plurality of rules. Therule 214 may indicate an operation to be performed on a number, letter, grammar, punctuation and/or syntax of theterm 232. Theclassification unit 210 may use therule 214 to match theterm 232 to at least one of a template and a pattern. For example, theclassification unit 210 may use a rule to classify aterm 232 as a social security number, if theterm 232 matches a particular pattern for a social security number, as indicated by therule 214. Thefilter unit 220 may block theterm 232 from being presented to the user 250, if theterm 232 is classified as a social security number. - In another example, the
classification unit 210 may perform an arithmetic operation on theterm 232. In turn, thefilter unit 220 may allow the term to be presented to the user 250, if a result of the arithmetic operation satisfies therule 214. For instance, theclassification unit 210 may classify theterm 232 as a credit card number upon a result of a checksum or multiplication of the digits of the credit card or instead classify theterm 232 as a date upon comparing a range and/or syntax of theterm 232 to a template. Here, thefilter unit 220 may block theterm 232 from being presented to the user 250, if theterm 232 is classified as a credit card number or a date that falls on prohibited day. - Machine learning 216 may relate to a construction and study of algorithms that can learn from data. Such algorithms may operate by building a model based on inputs and using that to make predictions or decisions, rather than following only explicitly programmed instructions. Machine learning 216 techniques may include, for example, grammar induction and/or a probabilistic classifier. For instance, the probabilistic classifier may be a Bayesian classifier. Grammar induction may include, for example, inference by trial-and-error, a genetic algorithm, a greedy algorithm, a distributional learning algorithm and a pattern learning algorithm. The
classification unit 210 may use machine learning to classify types ofterms 232 that may not be easily identifiable via arule 214, such as addresses or spam. - As noted above, the
classification unit 210 may determine a plurality of the different types ofclasses 212, based on the plurality of terms 232-1 to 232-n included in thedatabase 230. The types ofclasses 212 may relate to different security clearances. Further, at least one of theclasses 212 may be a subset of another of theclasses 212. Thus, thefilter unit 220 may compare to an identify of the user 250 toclass 212 of theterm 232 determine, if the user's security clearance only allows them to see a subset of theterms 232. If the user 240 does have not security clearance, thefiler unit 220 may not provide theterm 232 to the user 250, which was suggested by the database in response to the user's 250 query. - The
classification unit 210 may determine a plurality of theclasses 212 of theterms 232 simultaneously. Similarly, thefilter unit 220 may block and/or allow a plurality of theterms 232 simultaneously. Thus, examples may remove or preventterms 232 from being suggested to the user 250 that are classified as not to be presented to the user 250. Further, P11 is just one example of a type classification that could be filtered upon by thefilter unit 220. Examples may determine aclass 212 of aterm 232, based on any type of criteria deemed appropriate for denying to theterm 232. -
FIG. 3 is an example block diagram of acomputing device 300 including instructions for blocking a term based on a class of the term. In the embodiment ofFIG. 3 , thecomputing device 300 includes aprocessor 310 and a machine-readable storage medium 320. The machine-readable storage medium 320 further includesinstructions - The
computing device 300 may be included in or part of, for example, a microprocessor, a controller, a memory module or device, a notebook computer, a desktop computer, an all-in-one system, a server, a network device, a wireless device, or any other type of device capable of executing theinstructions computing device 300 may include or be connected to additional components such as memories, controllers, etc. - The
processor 310 may be, at least one central processing unit (CPU), at least one semiconductor-based microprocessor, at least one graphics processing unit (GPU), a microcontroller, special purpose logic hardware controlled by microcode or other hardware devices suitable for retrieval and execution of instructions stored in the machine-readable storage medium 320, or combinations thereof. Theprocessor 310 may fetch, decode, and execute instructions 321, 323, 325, 327 and 329 to implement blocking the term based on the class of the term. As an alternative or in addition to retrieving and executing instructions, theprocessor 310 may include at least one integrated circuit (IC), other control logic, other electronic circuits, or combinations thereof that include a number of electronic components for performing the functionality ofinstructions - The machine-
readable storage medium 320 may be any electronic, magnetic, optical, or other physical storage device that contains or stores executable instructions. Thus, the machine-readable storage medium 320 may be, for example, Random Access Memory (RAM), an Electrically Erasable Programmable Read-Only Memory (EEPROM), a storage drive, a Compact Disc Read Only Memory (CD-ROM), and the like. As such, the machine-readable storage medium 320 can be non-transitory. As described in detail below, machine-readable storage medium 320 may be encoded with a series of executable instructions for blocking the term based on the class of the term. - Moreover, the
instructions FIG. 4 . For example, the analyzeinstructions 322 may be executed by theprocessor 310 to analyze a term from a database (not shown) to determine a class, the term is to relate to part of a query and to suggest a remainder of the query. The determineinstructions 324 may be executed by theprocessor 310 to determine if the term is to be blocked in response to the query, based on the class of the analyzed term. The class may be determined based on at least one of a rule and machine learning. For example, the term may be blocked from being presented, if a user does not have permission to the analyzed class. The term may be allowed to be presented, if the user, if the user has permission to the analyzed class. -
FIG. 4 is anexample flowchart 400 of a method for blocking a term based on a class of the term. Although execution of themethod 400 is described below with reference to thedevice 200, other suitable components for execution of themethod 400 can be utilized, such as thedevice 100. Additionally, the components for executing themethod 400 may be spread among multiple devices (e.g., a processing device in communication with input and output devices). In certain scenarios, multiple devices acting in coordination can be considered a single device to perform themethod 400. Themethod 400 may be implemented in the form of executable instructions stored on a machine-readable storage medium, such asstorage medium 320, and/or in the form of electronic circuitry. - At
block 410, thedevice 200 receives aterm 232 from adatabase 230 related to part of a query of a user 250. Theterm 232 may suggest a remainder of the query. Atblock 420, thedevice 200 may classify the term based on at least one of arule 214 andmachine learning 216. Themachine learning 216 may include at least one of grammar induction and a probabilistic classifier to classify theterm 232. Therule 214 may match the term to at least one of a template and a pattern to classify theterm 232. - At
block 430, thedevice 200 blocks theterm 232 from being suggested, if theclass 212 of theterm 232 does not providepermission 222 to a user 250 to view theterm 232. Atblock 440, thedevice 200 allows the term to be suggested, if theclass 212 of theterm 232 does providepermission 222 to the user 250 to view theterm 232.
